Female rivalry in the workplace, has anyone experienced this?

Has anybody experienced animosity/jealousy from their co-workers or managers? More specifically women.

People act like it’s a small percentage. Please. I have seen this in every job I have worked at. There’s always this jealousy or meanness that takes place. They can’t stand to see another woman who is smart or successful or beautiful, it eats them up. Also the nicer you are the more they will hate you because they can’t make you look bad. If you are mediocre in any way they will like you because they feel good next to you, but when you stand out they can’t stand it.

Where does it stem from? Is it internalised misogyny? Is it insecurity? I’m interested to know the psychology behind this because it’s wild to me that grown women act this way.
